The Maytronics 9991594 Active Brush Holder Kit is a genuine OEM replacement assembly for the active-brush system used on select Dolphin robotic pool cleaners.

Installation / Use Notes

Disconnect the robotic cleaner from its power source before servicing. Access the active brush assembly according to the service procedure for your exact Dolphin model and replace the required holder-kit components in their corresponding positions.

Inspect the surrounding active brush and drive components while the cleaner is disassembled. Confirm that the replacement components are properly seated before returning the cleaner to service. Follow Maytronics service information applicable to your cleaner model.

Buy with Confidence

Benchmark Pool Supply helps pool owners and service professionals identify Maytronics Dolphin replacement parts by OEM part number, cleaner model, and repair application. That approach is especially useful for internal robotic-cleaner components where several similar-looking parts may be used across different generations.
